Reaction Steps

A mixture of ethyl 4-(2-bromo-4-fluorophenyl)-6-(bromomethyl)-2-(thiazol-2-yl)-1,4-dihydropyrimidine-5-carboxylate (0.96 g, 1.9 mmol), (2R,3S)-2-methylmorpholine-3-carboxylic acid (0.28 g, 1.9 mmol) and potassium carbonate (0.53 g, 3.8 mmol) in anhydrous ethanol (35 mL) was stirred at 25° C. for 12 hours under N2. The reaction mixture was filtered and the filtrate was concentrated in vacuo. The residue was purified by a silica gel column chromatography (DCM/MeOH (V/V)=15/1) to give the title compound as a yellow solid (0.48 g, 45%). The compound was characterized by the following spectroscopic data:
